This invention has to do With culinary beaters ci the type connnonlyused for Whipping; cream, beating;1 eggs and mining the ingredients insalad dressings, cnstards, light batters and siinilar liquids.

The beaters which heretofore have been inost extensively used `for thepurposes described have been characterized by an upright shalt, a bladesecured to the shaft near the loiver end thereol' tor insertion Within aliquid receptacle, and an operation niechanism connected with the shaltnear the upper end there-oit for rotating,` the blade.

ln the operation et such beaters, however, the upper and lower ends oi'the rotating shaft have asse-,inet the end thrust necessarilytransmitted through the beater in operating the saine against the bottomof a receptacle, with the result that a considerable amount ot the torcerequired to rotate the blade has been Wasted in friction at thosepoints, and a specially designed receptacle having,- a centeringindentation has been required.

The object of the present invention is to provide an improved beater oithe type described, which is light, strong; and durable in construction,is inexpensive to manufacture, will operate easily in any hind oivreceptacle with pra1tically no iriction, and may be readily t lienapart, either Ylor cleaning or tor subotitution ot differently shapedbut interchangeable blades.

@ther objects and advantages oi the invention will be evident to thoseskilled in the art upon a toll uncerstandin.;l oil the construction,arrangement and peration ot the iin proved beater.

One (nnbodinient of the invention is herein presented tor the purpose ofexenipliiication, but it will oit course be understood that theinvention susceptible et embodiment in other inodiiied 'liorlnsCorning;` equally within the comprehensive scope ot' the appendedclaims.

In the accompany drawing:

Fig. l is a side View of a beater constructed in accordance with theinvention; and

Fig'. 2 is a diiierent side vievv ot the saine, showing certain portionsthereof in section.

.lt will be observed in the drawing that the 1926. Serial No. ll.

ie same. A long rod is detachably secured i irough an aperture in alaterally bent por- "on lo et the strip and screwing),` into an apen urein another laterally bent portion 17, and provided at its lower end Withan enlarged head which is peripherally linurled to screwing' ot theupper end ol the into or out or the aperture in 'the por- A long;`tubular shalt l) is jour allot about the rod l5 oetivoen the laterallybent portion 1G the strip and the enlarged head lll on the rod. A pinion2O il secured to the upper end of the shalt 19' in inesh with the gearl2, and beating element in the liorni el a curved peritorate blade 2lsecured to the lower end oi the shaft.

ln operation, the beater is held in an upright josition, with the blade2l Within the receptacle conti 'ning the liquid to be beaten, and withthe head 18 against the bottom ot the receptacle. rlhe beater is heldlirnily in that position ineens ot the handle ll, and the crank handle'lfl is turned, resultingv in a rapid rotation of the blade 2l. rlliehead 18 on the lower end olf the rod l5 does not rotate with the bladebut is held stationary against he bottoni of the receptacle, and all end`lfrust in 'the beater is af'ssuined by the head, peunittiire` the bladeand its associated nievine parts to rotate with perfect lireedoni. In

order to ta ie the beater apart, 'tor the purpose oit' either cleaningor changing the blade, it is only necessary to unscrew the rod l5 a leivturns, whereupon the saine inay be Withdrawn, and the shaft 16, with itspinion and blade, removed.

I claim:

l. In a beater of the type described, a traine, a handle secured to the'traine for holding the saine stationary, a gear ournaled on the traine,a crank handle secured to the gear for rota-ting the saine, an extensionof the traine, a tubular shaft ournaled about the extension, a. pinionsecured to the shaft near one end thereof in mesh with the gear, abeating element secured to the shaft near the other end thereof, and anenlargement on the end of the extension for preventing the shaftjournaled on the extension from shifting axially, said enlargement beingremovable from the frame, a tubular shaft journalcd about the haft andbeating element.

2. In a beater of the type described, a frame, a handle secured to theframe for holding the same stationary., a gear ournaled on the frame, acrank handle secured to the gear for rotating the same, an extension ofthe frame a. tubular shaft journaled about the extension, a pinionsecured to the shaft near one end thereof in mesh with the gear, abeating element secured to the shaft near the other end thereof, and anenlargement on the end of the extension for preventing the shaftjournaled on the extension from shifting axially, said enlargement beingremovable from the frame together with the extension whereby to permitremoval of the shaft and beating element.

3.
